Samantha needs 4/5 yard of fabric to make costumes for the school play. Write and solve and equation to find how many costumes she can make with 8 yards of fabric.

Step-by-step explanation:

Samantha needs 4/5 yard of fabric to make costumes for the school play.

Let x represent the number of yards of fabric that she has

Let y represent the total number of costumes that she can make from x yards of fabric.

Since one costume require 4/5 yards of fabric, y costumes will require

x : 4/5 = x*5/4 = 5x/4

The equation will be

y = 5x/4

to find how many costumes she can make with 8 yards of fabric, it becomes

y = (5*8) / 4

y = 40/4 = 10
